  • Polymerization process with in-situ initiator formation
    Patent number: 8987391
    Abstract: A process for the polymerization of one or more monomers wherein at least one anhydride and at least one peroxy compound selected from inorganic peroxides, organic hydroperoxides, and peroxyacids are dosed during the polymerization reaction in a continuous or intermittent fashion to a reaction mixture comprising said monomers.
    Type: Grant
    Filed: June 27, 2011
    Date of Patent: March 24, 2015
    Assignee: Akzo Nobel Chemicals International B.V.
    Inventors: René Gerritsen, Jacobus Schut, Johannes Willibrordus Antonius Overkamp, Johannes Jacobus Theodorus De Jong

  • Continuous dosing of very fast initiators during polymerization reactions
    Patent number: 6639037
    Abstract: The invention pertains to a process wherein peroxides are dosed to a polymerization mixture, with essentially all of the organic peroxide that is used in the polymerization process having a half-life from 0.05 hour to 1.0 hour at the polymerization temperature. The dosing of such peroxide allows for accurate control of the polymerization rate, and the process will render a polymer with a low residual peroxide level.
    Type: Grant
